Check Digit Verification of cas no

The CAS Registry Mumber 146455-25-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,4,5 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 146455-25:
(8*1)+(7*4)+(6*6)+(5*4)+(4*5)+(3*5)+(2*2)+(1*5)=136
136 % 10 = 6
So 146455-25-6 is a valid CAS Registry Number.

SYNTHESIS OF 2',3'-DIDEHYDRO-2',3'-DIDEOXYNUCLEOSIDES UTILIZING COUPLING REACTIONS BETWEEN NUCLEIC BASES AND PHENYLTHIOSUBSTITUTED 2,3-DIDEOXYRIBOSE

Kawakami, Hiroshi,Ebata, Takashi,Koseki, Koshi,Matsumoto, Katsuya,Matsushita, Hajime,et al.

, p. 2451 - 2470 (2007/10/02)

Stereoselectivities in coupling reactions between silylated pyrimidine bases and 3- or 2-α-phenylthio-2,3-dideoxyribose were examined.In the former case, no stereoselectivies were observed when the coupling reactions were performed either with 1-chlorosugar in an SN2 mode or in the presence of Lewis acids as catalyst in an SN1 mode.Coupling reaction with 2-α-phenylthio-2,3-dideoxyribose in the presence of Lewis acids, especially SnCl4, proceeded with good stereoselectivity to give anomeric mixtures of α : β = 1 : 9.All these nucleosides were converted to 2',3'-didehydro-2',3'-dideoxynucleosides by oxidation to sulfoxides followed by thermal elimination of sulfenic acid.
